Using X-ray Energy Spectrum for Micro-analysing the Element of Walnut Seed Coat and Cotyledon

应用X-射线能谱微区分析法测定核桃种皮与子叶的元素含量。结果显示:核桃种子不同组织中共发现Mg、Al、Si、P、S、Cl、K、Ca、Fe九种元素。不同组织各元素分布含量有差异。子叶内层组织中S、K、P丰富,而子叶外层组织中K、Ca含量较丰富。各组织中K含量均较高。

The microanalysis on the element content of walnut seed coat and cotyledon was conducted with x-ray energy spectrum.The results showed that9elements:Mg ,Al ,Si ,P,S,Cl ,K,Ca and Fe were existed.The content and distribution were different in different tissue of walnut seed.The S,K and P in inner cotyledon and the K and Ca in outer cotyledon were abundant ,but the highest content in walnut seed was K element.
